Re: How to assign a common gateway IP to two vlans on an SRX4100? This was easy on MX/EX, seems impossible on SRX!
The SRX is basically assuming broadcast domains equal vlans by the time they arrive. So you would need to bridge the disparate vlans downstream of the SRX if that is where the gateway is going to exist.
You could do the bridge on the downstream mx without a gateway and use the bridge vlan assignment to connect up to the SRX for the common gateway. Assuming the path works out for that type of arrangement.
